Can my Tunze multicontroller do this?

[Doubledown]

I have 2 x 6100s and the 7095 multicontroller in a 72x24x24 tank and I am having difficulty with getting a setting I want. The pumps are on each side pane.

What I want is a low, constant flow for about 5 minutes interrupted by 10 seconds of high flow and then drop back to the low constant flow for 5 minutes. Ultimately the pumps would do this at the same time so that for those 10 seconds of high flow the entire tank would be turning over followed by a break for the corals to rest.

Is this possible and how do I set the controller to do this?

Thanks

Chris I would ask Roger from the Tunze forum. He can help out if anyone could. Mine is set on Interval two that pulses from 80% to 100% every five seconds. Meanwhile the other stream is only operating at 30%. The controller flip flops streams every eight minutes or so. This setting has worked well for me and my sps's have adjusted acordingly. It seems like a lot of people have there multicotrolers set on interval 2 w/ a pulse.

I-2 with a pulse also..

I have it set on I2, but I really don't know what the intervals are.

Who's up for a road trip to help a guy out?

Here's the response I got from Roger:

Looks like the best I can do is run the sequence mode and put both pumps on outlet 2b. If this is right, I can set the controller for 1 minute sequence intervals and have the pups on for 1 minute and off for 3 (or on for 30 secs and off for 90). This may not be enough time to generate the desired effect of a surge, but it just might work.

Wow that was a lot of conversation between you and Roger. By now you should be able to design your own multicontroller. Roger is really good help for answering Tunze questions!! I hope it works out for you! Great products....to have such a variety of settings.

Ran the test last night and it does function like I thought. When 1 pump is plugged into the last outlet (2b) it is turned on for 30 seconds and then off for 90 (approx). Now I just need to get a y-adapter to connect both pumps to outlet 2b and I should have the estimated effect.

Next question is will this be benneficial to the corals or not. I only ran one pump in the test for about 10 minutes (it was late) and I chickened out on leaving it that way through this evening so I am not sure if this will work. That will be another post/discussion though.
